I've realised that it's not a problem that's unique to OSM even, every map I've ever purchased that I know the area well enough has suffered from being out of date at time of publish anyway. I think OSM has the potential (with enough manpower) to be ahead of the game anyway. Even if people who don't actually map start using things like open street bugs to flag issues for people who do. At the moment the people reviewing the data are the people who regularly map and until we have a 'normal' set of data covering a whole metro area we won't get the many eyes and ears we need to catch all the little changes happening all the time. I have had about 6 people say they won't use it in Adelaide because there's just not enough coverage to make it replace a street directory, so the sooner we get 100% street coverage the sooner these kind of people will be on board and reporting the minor things we all miss. Nick, My worry with the Old map + yahoo combo is that some armchair mappers may over-ride existing surveyed data (I've already seen surveyed stuff over-ridden by someone looking at yahoo a few times) maybe even as far as changing the name to the old map name. :/ But I think the overall gains that will be made in getting the map to a basic usable state so the 'masses' can operate with it, and provide the detail feed back is more important. Until we have that we're just making a toy for ourselves and we can strive to make it perfect but it'll be useless to everyone else. -- =b _______________________________________________ Talk-au mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-au
